We finished the whole series. You might as well finish it now also. No spoilers, but we didn't find it too violent. The last episode explains a LOT. Such as: IF the nuking took place 200 years ago, how come a lot of the people are still alive? Who did the nuking, and why, etc.Have you watch more yet, I stopped at episode 5, not sure if I will finish it, started to feel like I was watching extreme violence first, while searching for a story to justify the violence.
